Kalyn Ponga a rare highlight in Queensland's State of Origin series defeat

The Maroons lost the 2018 State of Origin series with their 18-14 Game 2 defeat, but debutant Kalyn Ponga sounded a warning to the NSW Blues.

While Queensland failed to make the most of their chances in the second half, 20-year-old Ponga was a rare highlight. After coming on off the bench midway through the first half, he starred with 10 runs for 108 metres, he made a big line break that almost got him over the tryline, he had two offloads and made 26 tackles.

It was hardly obvious that it was Ponga's first time on the State of Origin stage, and during his post-game interview with Queensland legend Darren Lockyer, his response to a question about the difference between club football and Origin raised eyebrows.

State of Origin Highlights: NSW v QLD - Game II

"He got thrown into a foreign position in the middle of the field and his defence was as good as anyone's.

"He just wanted to get involved. He got the footy, he ran the footy.

"He just has a great attitude to go along with his talent. He's got a big future. We all know that don't we. That was certainly reassured tonight."

With Slater returning from a hamstring injury, the young fullback was picked on the bench and asked to perform as a roving utility. Even defending in the front line - something the Knights fullback has rarely done during his NRL career - he rarely missed a beat.

"Ponga what a freak to play big minutes in the middle," former NSW star Jarryd Hayne said on Twitter.

"Take a bow Kalyn Ponga. What a talent," league legend Darryl Brohman said.

Even Blues legend Peter Sterling was stunned at what Ponga produced on the night.

"We didn't know how Kalyn Ponga was going to be used, but he played in the front line, and nearly won the game for his side," Sterling told Wide World of Sports.

"He's a rare talent. He's an outstanding young man.

"He's the youngest Queensland player to make his debut since Israel Folau 10 years earlier. This is the first of many Origins for him.

"I think we're all excited to see his involvement."

It's music to Maroons fans' ears with the future definitely bright for Queensland.
